COOKING-STOVE.

The Schedule referred to in these Letters Patent and making part of the some.

I, 'FRAsoIs H. Root, of the city of Butialo, in'the county of Erie and State'of New York, have invented a certain Improvement in Cooking-Stoves, of which i the following is a specification.

My invention consists in the construction of the front port-ion of the stove above the gratewith aforward projection, having an, inclined or convex bottom and an inclined or concave roof, provided with dormer i windows, whereby'the mica, of which the latter are composed, 'is removed from the intense heat of the fire, which would otherwise soon destroy the same.

In the accompanying drawings- Figure I is a vertical section of the forward portion of a cooking-stove embracing my improvement.

Figure II is a front elevation thereof.

Figure 111 is a sectional plan.

Like letters of reference designate like partsin each of the figures. A

A represents the firechamber.

B, the grate.

l O, the forward part of the oven.

and l E, the dormer windows formed in the roof thereof. lhe projection D is shown as commencing at the base of "the fire-chamber, and extending forward with an upwardly-inclined or curved base, 0, which terminates at a point aboutone-third of the distance from the base of the fire-chamber to the top plate of the store. l r I From the termination of the plate a, which forms a portion of the front as well as the. .bottom' of the extension, a'receding inclined, or, preferably, slightly concave plate, 0', connects with the'front of thetire-chamberjat the top of the stove, and forms the roof or cover.

of this extension, 1).;

l D, the projection in front 'of and above the grate;

The dormer windows E are formed by the projection of an arched frame, a, from the roof-plate c, the

'mica being secured in said framein a common manner.

I prefer to make the covering 0' of the exteuson so that portions of it will slide horizontally, and thus furnish at this point an opening and way of access into the fire-pot, In such case the windows E are made in, and so as to project from the sliding portions, as represented in the drawings.

The forward extension 1) of the fire-pot removes the front portion of D away from the lines of draughtand moreiiitense heat of the fire the coal natnrallyvassuming the position shown in fig. 1, whichalsorepresents the lines of the draught, which, being baclc ward,'leawesthe temperature of the front of the extension comparatively low.

The backwardlyinclined or'concave plate c"con' forms to'a greater or less extent with back plate of the fire-pot and the'natural direction of thedraught, and produces a desirable form of fire-pot,- while the projection of' the windows from said inclined plate, in connection with the forward extension D, so'removes the mica from the influence ofthe fire as to render the windows. practicable and enduring.

I do not claim the dormer windows or inclined or curved roof-plate by themselves, as I am aware that they have been previously known and used in a stove called the Mansardf but Y \Vhat I claim as my'invention isv The forward extension Dyprovided with dormer windowsE, projecting from the receding-plated, as and for t-he purpose hereinbeforc setforth.
